As of 2015, hospital readmission rates are calculated for which of the following conditions?

The correct understanding of hospital readmission rates as of 2015 indicates that they are primarily focused on specific conditions that significantly impact patient outcomes and healthcare costs. Among the options provided, the most widely recognized conditions for which readmission rates are calculated include heart failure, pneumonia, and acute myocardial infarction. These conditions are linked to substantial mortality and morbidity, making their readmission rates critical indicators for evaluating the quality of care.

While total knee arthroplasty (TKA) and total hip arthroplasty (THA) are important surgical procedures with their own risks and complications, the specific calculation of readmission rates within the context of the 2015 guidelines is more rigorously applied to medical conditions like heart failure, pneumonia, and acute myocardial infarction. These conditions are associated with higher rates of hospital readmission and are often the focus of performance metrics for hospitals.

Thus, the focus on heart failure, pneumonia, and acute myocardial infarction reflects broader healthcare priorities aimed at reducing hospital readmissions in these areas, which have direct implications on patient health outcomes and healthcare expenditures.
